Industrial 4-Channel RS485 Hub Expansion Module, Isolated RS485 Relay with Wide Baud Rate, Rail-Mount Support for IoT Gateway, Data Acquisition, Sensors, and Automation

Overview The RS485-HUB-4P is an industrial-grade 4-channel RS485 expansion hub designed for robust communication networks and IoT gateway applications. It allows a single RS485 master port to control four isolated RS485 sub ports, providing reliable signal relay, network extension, and isolation functions. Equipped with optoelectronic isolation, this industrial RS485 hub effectively separates master and sub devices, protecting against electrostatic shocks, lightning strikes, and voltage surges. This ensures stable and secure operation even in harsh industrial environments. The hub supports a wide baud rate range of 300460800bps, allowing seamless communication with various RS485 devices, from low-speed sensors to high-speed industrial controllers.

This makes the 4-channel RS485 relay module ideal for automation, monitoring, and IoT deployments. Installation is simple and convenient with rail-mount support, compatible with 35mm standard guide rails. The hub features screw terminals for power input, providing a secure and durable connection for industrial setups. The RS485-HUB-4P is widely used in data acquisition, sensor networks, industrial automation systems, intelligent instrument monitoring, and IoT gateway expansion, delivering stable and reliable RS485 signal amplification and relay control. Its cost-effective design, industrial isolation, and wide compatibility make it an essential tool for engineers and system integrators.
